IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No.

138,057, dated April 22, 1873 application filed March 3, 1873.

To all whom it may concern:

Be it known that I, LYMON A. TUTTLE, of Berea, in the county of Ouyahogaand State of Ohio, have invented a certain new and ImprovedSash-Fastener, of which the following is a description:

Figure l is'a side view of the window-fastener secured to the window.Fig.2 is a view of the fastener detached therefrom.

Like letters of reference refer to like parts in the several views.

The purpose of this invention is to hold up a window-sash and to fastenthe same when down so that it cannot be raised from the outside; and itconsists in the peculiar construction, arrangement, and mode ofoperation, as follows, viz:

A in Fig. 2 represents a plate having therein a slot, B, of the shapeshown. 0 is a cam, which is secured, in connection with the plate, by ascrew, a, passing through it and into the slot, and thence into the sideof the sash, as.

shown in Fig. 1. On one side of the plate referred to is formed a rib orshoulder, D, the outer edge E of which is straight and plain, whereasthe inside edge or shoulder is made to consist of two incline planes, FG, the incline being from the ends toward the middle, as shown in Fig.2.

' It will be observed that the direction of the slot coincides with thatof the incline planes.

The above-described fastener is secured to the side of the sash by thescrew a, and in such manner as to bring the side E against the face ofthe casin g H, Fig. 1. In order to move the sash in either direction thecam is so turned as to bring the shortest radius toward the inclineplanes. This will allow a free movement of the sash, so that it can beraised or lowered, and which may be retained at any one particularheight by turning the cam, so as to bring the longest radius against theshoulders or incline planes, the result of which will be to crowd therib D against the casing, and brace the sash in the window-frame, andprevent it from being moved downward, as the incline plane G will wedgeagainst the cam in consequence of the weight of the sash and therebyhold up the window. Also when the window is down it is locked by turningthe cam, so as to bring its longest radius to the lower incline plane F,which, in like manner, will wedge between the cam and casing, andprevent the window from being pushed up.

This window-fastener is simple in its construction and manner ofoperation, and it is also very easily attached to the sash, requiringfor that purpose but little mechanical skill and labor.
